Illustration of standard atmospheric pressure
14.5 psi (100 kPa) is comparable to standard atmospheric pressure at sea level (101.325 kPa).

Did you know? Standard atmosphere (1 atm) is 101.325 kPa.

Sea-level atmospheric pressure is 101.325 kPa = 14.696 psi = 760 mmHg = 1 atm exactly.

How to Convert Bar to KPa

1 bar = 100 kPa exact

KPa = Bar × 100

Example: 1 bar × 100 = 100 kPa

Reverse Conversion

To convert kPa back to bar:

  • Remember, 1 kPa equals 0.01 bar.
  • To convert 100 kPa to bar, multiply 100 x 0.01, resulting in 1 bar.

exact This conversion factor is exact by international definition.
